Packaging containers

Abstract

This product is a container assembled by folding and gluing a blank sheet made of paper or synthetic resin (see the reference plan view in the unfolded state and the reference bottom view in the unfolded state). This product has a main body having a bottom and sides, and a lid that closes the top opening of this main body in an openable manner. The closed state is stably maintained by inserting a tab formed on the main body into a slit formed on the free end side of the lid. The lid is configured to form a recess in the upper part of this product in the closed state by a first fold line on the base side connected to the main body and a second fold line on the free end side, and multiple products can be stably stacked by fitting the bottom of the product located above into the recess of the product located below, as shown in the reference perspective view of the stacked state. The two sides of the lid are raised by the third fold line to the same dimension as the depth of the recess, and by inscribing the two raised sides with the sides of the main body, the position of the lid in the closed state can be stably maintained. The lid has a rectangular window hole, which is covered with a transparent film attached to the inner surface of the lid.
